ocean. There they in due time breed, and from their eggs are 

 hatched the young Leptocephali, which, after attaining a certain 

 size, cease to feed, and assume the very different form of the elver. 

 The possibility of establishing these remarkable facts depended on 

 the powerful oceanic currents that prevail about the Straits of 

 Messina, bringing up occasionally to the surface the inhabitants of 

 the depths of the sea. Grassi was thus able to obtain from, time 

 to time both adult eels with fully developed sexual organs and their 

 larval progeny, and he actually observed in an aquarium the develop- 

 ment of a Leptocephalus brevirostris into an elver. 



Such highly meritorious contributions to evolution are fitly recog- 

 nised by the award ot the Darwin Medal.
